What Factors Control Carbon Mineralization and Flux in Bog Soils and Ho

I. Presentation: What is a Bog? Bog, from the old Gaelic bogach, is generally used to allude to any stretch of waterlogged, marshy ground. The words, fen, moor, muskeg, peatland, and soil are additionally used to portray these regions, which can prompt some disarray over phrasing. In particular, a marsh is a peat collecting wetland that has no critical inflows or outpourings and supports acidophilic greeneries, especially sphagnum (Gosselink and Mitsch 1993). By far most of swamps are situated in the wet, cool boreal areas of North America and Eurasia. Marshes are likewise called peatlands as a result of the peat they amass, however peatland is a progressively broad term that incorporates minerotrophic and change peatlands. These wetlands likewise collect peat, however they vary geologically and hydrologically from marshes. Genuine marshes (ombrotrophic peatlands) are portrayed by peat layers higher than their environmental factors; they are regularly called raised swamps. They likewise get supplements and minerals only by precipitation, for example they are hydrologically disconnected (Gosselink and Mitsch 1993 p.374). They structure in an assortment of ways, yet once ombrotrophic (downpour fed) peatlands create they are steady under genuinely wide ecological variance (Gosselink and Mitsch 1993 p.372). This conversation will be restricted to the genuine marshes, and they will be alluded to as lowlands or peatlands. II. Peat Soils and Carbon Mineralization Peat is the name for the dirt that structures in swamps and different peatlands. It is a natural soil (Histosol), made as a rule out of in part rotted plant matter. The high level of natural strands in peat makes it a fibrist, which is a Histosol containing short of what 33% rotted natural issue... ... the peat. Journal of Ecology 81 (1993), 615-625. Siegel, D.
